Canada: I need a postal code for an estimate. (Lettermail/Expedited/Xpresspost prepaid mailer)USA: I just need your state. (physical size and total $ value will determine Air/Surface/Light Packet)Overseas: Need your country. (Airmail only. I've had terrible luck shipping things to Italy, Mexico, South/Central America and India. Those countries/areas will need to use Xpresspost w/signature option, which can get pricey!)
